Research focussed on understanding the isospin symmetry and some of the key properties of the nuclear force, such as the charge asymmetry and the charge dependence of the nuclear force. In particular, I participated in the lifetime measurements of 46V and 46Ti, I am responsible for the ongoing spectroscopy study of 94Ag via the p,3n evaporation channel and I assisted three graduate students with their knock out and p2p analysis. I also contributed to the preparation of an accepted proposal for the HiCARI campaign in RIKEN.

Recent experiments have evidenced the existence of new nuclear shell gaps at N=14 and N=16 in neutron-rich oxygen isotopes associated with the vanishing of the N=20 shell gap. However, in the neutron-rich carbon isotopes, the extent to which these gaps persist is unclear. In an effort to answer this question we have attempted to probe the low-lying level structure of 17C using the (d,p) transfer reaction to locate the single-particle orbitals involved in the formation of the N=14 and N=16 shell gaps. The experiment was carried out at the GANIL facility. A 16C beam at 17.2 AMeV produced by fragmentation was used to bombard a CD2 target. The light ejectiles were detected using the TIARA silicon strip array while a Si-Si-CsI telescope was placed at zero degrees to identify beam-like residues. In addition, four HPGe-EXOGAM clover detectors were used to measure the gamma-rays arising from 17C bound excited states. The measured angular distributions confirm the spin and parity assignments of 3/2+, 1/2+ and 5/2+ for the ground and the first and second excited states located at 217 keV and 335 keV respectively. The spectroscopic factors deduced for these excited states indicate a large single particle strength, in agreement with shell model calculations. With a strong l=0 valence neutron component and a low separation energy, the first excited state of 17C appears as a good one-neutron halo candidate.
